Denitrification, activity of bacterial flocs, and growth of a filamentous bacterium in relation with the bulking of activated sludge [PDF]
, 1978 Activated sludge with poor settling characteristics is caught under the term "bulking" sludge. Various types of bulking activated sludge can be distinguished.1) Sludge containing an abundance of filamentous microorganisms.2) Sludge, characterized by ...

Nitrite reductase activity of nonsymbiotic hemoglobins from Arabidopsis thaliana.
Biochemistry, 2012 Plant nonsymbiotic hemoglobins possess hexacoordinate heme geometry similar to that of the heme protein neuroglobin. We recently discovered that deoxygenated neuroglobin converts nitrite to nitric oxide (NO), an important signaling molecule involved in ...

Microbially Influenced Corrosion in Epoxy‐Ceramic Coated Carbon‐Steel Cooler
Materials and Corrosion, EarlyView.A significant localization of corrosion attacks up to 1 mm deep were found in coated carbon‐steel cooler. Corrosion products and biofilm were enriched in mixed bacterial community including the genera Sulfuritalea and Methylotenera. Analysis of metabolic markers confirmed their coexistence with sulfate‐reducing bacteria.

The relationship between redox enzyme activity and electrochemical potential—cellular and mechanistic implications from protein film electrochemistry [PDF]
, 2011 In protein film electrochemistry a redox protein of interest is studied as an electroactive film adsorbed on an electrode surface. For redox enzymes this configuration allows quantification of the relationship between catalytic activity and ...

Virus-Encoded Ribonucleotide Reductases [PDF]
arXiv, 2014 Ribonucleotide reductases are encoded by many viruses, but without other enzymes of nucleotide metabolism of no obvious use. A look at the enzymes' molecular properties and their possible mutator action may give clues.

How native state topology affects the folding of Dihydrofolate Reductase and Interleukin-1beta [PDF]
, 2000 The overall structure of the transition state and intermediate ensembles experimentally observed for Dihydrofolate Reductase and Interleukin-1beta can be obtained utilizing simplified models which have almost no energetic frustration. The predictive power of these models suggest that, even for these very large proteins with completely different folding

Responsive Materials, EarlyView.By simulating the host defense strategy of human α‐defensin 6, biomimetic transformable peptide‐based aggregation‐induced emssion nanomaterials (PBANs) were prepared. PBANs self‐assembled into nanoparticles under physiological conditions, and in situ transformed into nanofiber on bacterial surfaces through receptor‐ligand interactions in infected ...
